88-12-0 Description |
|
N-vinyl-2-pyrrolidone (NVP) is commonly used as a reactive diluent for radiation curing in UV-coating, UV-inks, and UV adhesives. It is used as a monomer to produce water soluble polyvinylpyrrolidone (PVP) with uses in pharmaceuticals, oil field, cosmetics, food additives & adhesives. It is used in the manufacture of copolymers with, for example, acrylic acid, acrylates, vinyl acetate and acrylonitrile and in the synthesis of phenolic resins. 1-Vinyl-2-pyrrolidinone is a colorless to yellow liquid, with a characteristic odor. Its melting point is around 13.5oC and boils at about 90-92oC. VP is completely miscible in water and in most organic solvents but partially miscible in aliphatic hydrocarbons. Industrial production of VP by reacting 2-pyrrolidone with acetylene at high pressure and temperature has been reported. The vinylation process proceeds in liquid phase and is catalyzed by 3-pyrrolidone -potassium hydroxide. |

88-12-0 Safety Profile |
|
88-12-0 Safety ProfileConfirmed carcinogen. Moderately toxic by ingestion, inhalation, and skin contact. A severe eye irritant. Probably irritating and narcotic in high concentrations. Combustible when exposed to heat or flame; can react vigorously with oxibzing materials. To fight fire, use alcohol foam, CO2, dry chemical. When heated to decomposition it emits highly toxic fumes of NOx. |
